Winterizing a house trailer, also known as a mobile home, is crucial to prevent costly damage from freezing temperatures and ensure your comfort throughout the colder months. Properly winterizing involves protecting your plumbing, insulation, and overall structure from the elements, safeguarding your investment and allowing you to enjoy your mobile home for years to come.
The Importance of Winterization
The potential consequences of neglecting winterization are significant. Freezing pipes can burst, leading to extensive water damage. Inadequate insulation results in higher heating bills and uncomfortable living conditions. Damage to skirting can expose the underbelly to drafts and pests. Therefore, proactively preparing your mobile home for winter is a worthwhile investment in both time and money. This guide provides a step-by-step approach to thoroughly winterizing your house trailer.
Protecting Your Plumbing System
The plumbing system is the most vulnerable aspect of a house trailer during winter. Water expands when it freezes, putting immense pressure on pipes and fixtures. The following steps are crucial for preventing frozen pipes:
Draining the Water System
- Shut off the main water supply. This is typically located outside the trailer, either at the water meter or at a designated shut-off valve.
- Drain the hot water heater. Turn off the breaker to the hot water heater and open the drain valve at the bottom. Let all the water drain out completely. Be sure to open a hot water faucet inside the trailer to allow air to enter the tank, facilitating drainage.
- Drain all faucets and toilets. Open all faucets (both hot and cold) inside the trailer, including the shower and any outside faucets. Flush all toilets until the tanks are empty.
- Bypass the water heater (if applicable). Many newer mobile homes have a bypass valve that allows you to isolate the water heater from the rest of the plumbing system, preventing antifreeze from entering it. Consult your owner’s manual for instructions on how to use the bypass valve.
- Use an air compressor to blow out the lines. This is the most effective way to ensure that all water is removed from the pipes. Connect an air compressor to the water inlet connection and gradually increase the pressure (no more than 40 PSI) to force any remaining water out through the faucets. Open and close each faucet individually to ensure thorough clearing. Remember to close the faucets and drain plugs after blowing out the lines.
Adding Antifreeze to Plumbing Fixtures
- Pour RV antifreeze into all drain traps. This includes the kitchen sink, bathroom sink, shower, and toilet. RV antifreeze is non-toxic and designed specifically for plumbing systems. Never use automotive antifreeze as it is toxic and can damage your plumbing.
- Pour RV antifreeze into the toilet bowls. Add enough antifreeze to cover the bottom of the bowl and protect the trap.
Protecting Exposed Pipes
- Insulate exposed pipes. Pipes located under the trailer or in unheated areas are particularly susceptible to freezing. Use pipe insulation sleeves or heat tape to protect these pipes.
- Heat tape with thermostat. Consider using heat tape with a built-in thermostat for optimal protection.
Insulating and Sealing Your Home
Proper insulation is essential for maintaining a comfortable temperature inside your house trailer and reducing energy costs. Sealing any gaps or cracks prevents drafts and keeps the cold air out.
Skirting and Underbelly
- Ensure proper skirting. Skirting around the base of the trailer prevents cold air from circulating underneath. Make sure the skirting is in good condition and securely attached. Repair any cracks or gaps.
- Insulate the underbelly. Consider adding insulation to the underbelly of the trailer to further protect the pipes and reduce heat loss.
Windows and Doors
- Caulk and weatherstrip windows and doors. Seal any cracks or gaps around windows and doors with caulk and weatherstripping. This will prevent drafts and improve energy efficiency.
- Use window film or plastic sheeting. Apply window film or plastic sheeting to the inside of windows to add an extra layer of insulation.
- Use draft stoppers at doorways. Place draft stoppers at the bottom of doorways to block cold air from entering.
Insulation Upgrade
- Attic insulation. Adding extra insulation to the attic can significantly reduce heat loss. Check the existing insulation and add more if needed.
- Wall insulation. While adding wall insulation can be a more complex project, it can significantly improve the overall energy efficiency of your mobile home.
Additional Winterization Measures
Appliances and Storage
- Remove perishable food. Clean out the refrigerator and freezer and remove any perishable food items.
- Prop open refrigerator and freezer doors. This prevents mold and mildew from growing inside.
- Turn off the propane tank (if applicable). If your trailer uses propane, turn off the main tank and bleed the lines.
- Remove batteries from smoke detectors and carbon monoxide detectors.
Exterior Preparation
- Trim trees and shrubs. Trim any trees or shrubs that are close to the trailer to prevent damage from snow and ice.
- Clear gutters. Clean out the gutters to prevent ice dams from forming.
- Check the roof. Inspect the roof for any damage or leaks. Repair any issues before winter arrives.
Frequently Asked Questions (FAQs) about Winterizing a House Trailer
FAQ 1: Can I use regular antifreeze instead of RV antifreeze?
No, absolutely not. Automotive antifreeze is highly toxic and can contaminate your water system, making it unsafe for consumption. Only use RV antifreeze, which is specifically formulated for plumbing systems and is non-toxic.
FAQ 2: How much RV antifreeze do I need?
The amount of RV antifreeze you need will depend on the size of your plumbing system. A good rule of thumb is to have at least 2-3 gallons on hand for a small to medium-sized house trailer.
FAQ 3: Do I need to drain my washing machine and dishwasher?
Yes, you should drain your washing machine and dishwasher to prevent water from freezing in the pumps and lines. Follow the manufacturer’s instructions for draining these appliances. You can also add a small amount of RV antifreeze to the dispenser of each appliance.
FAQ 4: How do I protect my water pump?
After draining the water system, add a small amount of RV antifreeze to the water pump to protect its internal components. You can do this by pouring antifreeze into the pump’s inlet line. Run the pump briefly to circulate the antifreeze.
FAQ 5: What if I don’t have an air compressor to blow out the lines?
While an air compressor is the most effective method, you can still winterize your plumbing system by draining it thoroughly and adding RV antifreeze to all the fixtures. However, it’s essential to ensure all standing water is eliminated.
FAQ 6: How often should I check on my winterized house trailer?
Ideally, you should check on your winterized house trailer every few weeks, especially after periods of extreme cold or heavy snowfall. This will allow you to identify any potential problems early on.
FAQ 7: Can I leave my thermostat set low during the winter?
Yes, you can leave your thermostat set to a low temperature (around 50-55 degrees Fahrenheit) to prevent pipes from freezing. This is especially helpful if you are not draining the water system completely. However, this will also increase your energy costs.
